This invention relates to toy aeroplanes, and 4 and is secured in place by nuts 13 and the purpose of the improved construction threaded on its rear end. Any slight necesis to provide for rotation of a substantial sary adjustment ofthe rear body section 3 part of the body portion of the device, beartoward or away from the intermediate body Q ing pictures or the like or having variously s'ect1on l-can be effected by virtue of slot and 55 colored portions adapted to attract a childs bolt connection 78 between the bar and V attention when rotated; and it consists of the rearbody section 3. The rotatable interthe construction and arrangement of parts mediate section l is secured to the propeller in general and detail, as more fully hereinshaft by means of a. flanged sleeve 13 keyed after described and claimed. 7 to the shaft" by key 14, the flange 15 of the 60 In the accompanying drawings: sleeve being bolted to the forward end wall Figure 1 is a side view of a toy aeroplane ofth'e section 4.

The intermediate rotatable sect-ion propeller shaft by drawing the device over the 4, is slightly contracted at each end as at 9 floor, the clutch 31, will be moved into en- 7 and 10 to fit loosely within the respective gagement'with the hub of the drum 28. Any

front and rear body sections 2 and 3 thus suitable means as shown by chain dotted lines maintaining the cylindrical stream lineconmay be provided for manually shifting the tour throughout the entire length of the body. clutch into andout of engagement with the A propeller shaft 11 carrying a propeller drum. When the drum 28 has been fixed to V 12 on its forward end extends axially through the propeller shaft, by appropriate move the end walls of the respective sections 2, 3 ment of the clutch, 'rotationof the wheels 16 causes the body section 4 to rotate, much to the interest of the operatorwhose attention will immediately be attracted by the action thus set up also by the changing colors.

The spring gear mechanism 26, previously referred to is mounted in a housing 32 positioned within and fixed to the forward body section 2. It consists of a large gear33 and a pinion gear 34, fixed to a short shaft 35, the

ends of which extend loosely into substantially vertical short slots36, formed in the opposing vertical walls of the housing. The short shaft 35 normally seats by gravity in the bottom of slots 36 thus maintaining gear 33 normally out of engagement with a small pinion gear 37, mounted on the flanged sleeve 13, previously referred to. A trigger 38, secured intermediate its ends upon I a short shaft 39, mounted for rotation in the housing 32, is formed with a finger grip 40 and a toothed segmental portion 41, the latter engaging the pinion 34. Operation of the propeller shaft by means of the mechanism'is effected as follows:

The operator holds the device in one hand by grasping the plane 20 or one of the brackets 18, and after placing the thumb of the other hand against the depending extension 42 formed on theforward body portion for this purpose, presses the trigger inwardly to the dotted line position illustrated in Figure 4. This causes the toothed portion 41 to ride up over and rotate the pinion 34 and to also elevate the shaft 35 in slots 36, thus moving gear 33 into mesh with pinion 37. It will thus be seen that actuation of the trigger in the manner described causes rotation of the propeller shaft. When finger pressure on the trigger is released, the shaft 35 will drop by gravity to the bottom of slots 36, and the trigger will be returned to its original set or full line position by means of spring 43. A stop 44 on the trigger engages the housing and limits the extent of this return move ment, It is desirable that the running gear be disconnected from the propeller shaft prior to actuation of the trigger but this is not necessary.

It will be understood that by making slight changes, in the forward body section 2, that the device could be mounted on the radiator cap of an automobile. When so mounted the propeller 12 will have suificient propelling force to rotate the body section 4.

Having thus described my invention what I claimas my invention is:

1. A toy aeroplane having a symmetrically shaped body comprising front and rear sections and an intermediate section, a propeller shaft fixed to and mounted .for rotation with said intermediate section, means for maintaining the ends of said intermediate section in spaced relation to the opposing ends of the said front and rear sections, and means for rotating the propeller shaft.
